QUESTION
How to use Twilio to voice call from browser pc to esp32? I want to find ways to telemedicine with esp32-cam to stream video and now I'm finding for audio stream too, please suggest me.
...ANSWER
Answered 2021-Apr-20 at 04:08Twilio developer evangelist here.
The Twilio Voice SDKs and the Twilio Video SDKs both support iOS, Android and web browsers. There is no support for Arduino/esp32. If you can run a web browser on the esp32, then you might be able to use the JavaScript SDKs.
QUESTION
Does anyone know what went wrong with my code? I'm trying to use Python to control esp32cam but I don't know what went wrong.
Sorry, I'm not sure if I'm posting this correctly as it's my first time asking! This is my code.
I changed the code after Dr.Casual helped (thanks alot btw!) but I'm still having errors. Updated the code.

QUESTION
I have an ESP8266-12e and an ESP32-CAM. I am trying to send data from the 12e to the ESP32 through serial connection. I have connected TX of 12e to RX of ESP32 and RX of 12e to TX of ESP32. They are both powered by the same source 3.3v for 12E and 5v for ESP32. A common ground.
I have both set to a baud rate of 115200.
This is the code for the ESP-12e

QUESTION
I am currently experimenting with the ESP32-CAM, which is a microcontroller with integrated camera that you can program through the Arduino IDE (with C++11). For capturing images with the cam, there is a library called 'esp32cam', which contains the function esp32cam::capture(). This function apparently returns a variable with the type std::unique_ptr. There is also an example sketch, which saves the returned frame in a local variable of the type auto:

I'm a DIYer and I'm trying to upload a picture from ESP32-CAM to imgbb.com using POST. This project from RandomNerdTutorials gave me a better notion about POST request on C++.
I took their code and modified it to upload to https://api.imgbb.com.

QUESTION
I've been trying to build a micropython for esp32-camera and I keep getting errors during the make process when building some of the drivers in the mp/ports/esp32/modules directory. The error I get is a syntax error. For example there's a file named ntptime.py in this directory and it contains a single line: ../../esp8266/modules/ntptime.py and that results in "SyntaxError: invalid syntax" I've programmed python for a while, but am not familiar with this concept and don't understand how it can work, but maybe it can? I'm not familiar with doing that and since it's not working when I run make, maybe there's something setup-wise that I've missed or whatever. Can anyone shed some light on this practice and explain under what circumstances this works to direct make (or the python compiler) to resolve this statement by loading the source from the directory specified in that single line of code.
...ANSWER
Answered 2020-Jun-17 at 13:38Duh, can't believe I missed this: there "files" are symbolic links; I should've remembered that, but alas, I'm getting older by the minute! Still, it doesn't answer the question as to why they weren't being recognized during make but instead throwing a SyntaxError; but I'll leave that for another day.
QUESTION
I am trying to compute optical flow (lucas kanade - based) on an esp32-cam. I tried to save memory by operating on 2 small buffer of array only. I still have an error corrupt heap:
test0
bfore allocate out conv
after allocate out conv
bfore allocate out conv
after allocate out conv
bfore allocate out conv
after allocate out conv
bfore allocate out conv
CORRUPT HEAP: multi_heap.c:432 detected at 0x3fff7114 abort() was called at PC 0x40090a7f on core 0
Here is my code composed of 1D convolution and transpose to perform separate equivalent 2D convolution:
...ANSWER
Answered 2020-Apr-17 at 17:37With w and h not being the same, transpose will access and write to out-of-bounds memory.
From your comment, you have w at 96 and h at about 48. The second parameter to swap in transpose will access up to f[w * (w - 1) + h * (h - 1)] which is past the w * h elements you've allocated. This will change memory that hasn't been allocated, and in your case is corrupting the data your library uses to keep track of allocated memory (which is only detected during an allocation of free, and may not get detected right away).
The solution involves rewriting transpose to properly transpose a rectangular matrix. (This involves swapping w and h for the returned matrix.)
